In the world as we know it, once you have given something away, it is no longer yours. But in the spiritual realm, all that you give is given to yourself and all that you withhold is withheld from you. As you give love, you receive love. As you give peace, you receive peace. Notice how just knowing this changes both your perception and your experience.
All that I give is given to myself.
Today's idea, completely alien to the ego and the thinking of the world, is crucial to the thought reversal that this course will bring about. If you believed this statement, there would be no problem in complete forgiveness, certainty of goal, and sure direction. You would understand the means by which salvation comes to you, and would not hesitate to use it now.
Let us consider what you do believe, in place of this idea. It seems to you that other people are apart from you, and able to behave in ways which have no bearing on your thoughts, nor yours on theirs. Therefore, your attitudes have no effect on them, and their appeals for help are not in any way related to your own. You further think that they can sin without affecting your perception of yourself, while you can judge their sin, and yet remain apart from condemnation and at peace.
When you "forgive" a sin, there is no gain to you directly. You give charity to one unworthy, merely to point out that you are better, on a higher plane than he whom you forgive. He has not earned your charitable tolerance, which you bestow on one unworthy of the gift, because his sins have lowered him beneath a true equality with you. He has no claim on your forgiveness. It holds out a gift to him, but hardly to yourself.
Thus is forgiveness basically unsound; a charitable whim, benevolent yet undeserved, a gift bestowed at times, at other times withheld. Unmerited, withholding it is just, nor is it fair that you should suffer when it is withheld. The sin that you forgive is not your own. Someone apart from you committed it. And if you then are gracious unto him by giving him what he does not deserve, the gift is no more yours than was his sin.
